1 answer:

4 0

Rewrite 49x249x2 as (7x)27x2.(7x)2−47x2-4Rewrite 4 as 2^2.(7x)^2−2^2Since both terms are perfect squares, factor using the difference of squares formula,
a^2−b^2=(a+b)(a−b) where a=7x and b=2.(7x+2)(7x−2)

Express the polar coordinates (2,3pi/4) as Cartesian coordinates

Rus_ich [418]

The Cartesian equivalent of the polar coordinates (r, theta) is

(r cos t, r sin t), where t = theta.

So, (2, 3pi/4) becomes

(2 cos(3pi/4), 2 sin(3pi/4))

(2 • -sqrt{2}/2, 2 • sqrt{2}/2)

Answer: (-sqrt{2}, sqrt{2})

Done.

Note: sqrt = square root for short.
